I haven't done any research on this, but I believe that once this is produced it will be the first appearance of Schopenhauer in any theatrical production, certainly on the NY stage.
Schopenhauer has an opinion on theatre, as on almost everything else. From his The Art of Controversy (aka "The Art of Being Right"):
A drama or a novel may often attract us by its interest, and yet be so utterly deficient in any kind of beauty that we are afterwards ashamed of having wasted our time on it. This applies to many a drama which gives no true picture of the real life of man; which contains characters very superficially drawn, or so distorted as to be actual monstrosities, such as are not to be found in nature; but the course of events and the play of the action are so intricate, and we feel so much for the hero in the situation in which he is placed, that we are not content until we see the knot untangled and the hero rescued. The action is so cleverly governed and guided in its course that we remain in a state of constant curiosity as to what is going to happen, and we are utterly unable to form a guess; so that between eagerness and surprise our interest is kept active; and as we are pleasantly entertained, we do not notice the lapse of time. Most of Kotzebue’s plays are of this character. For the mob this is the right thing: it looks for amusement, something to pass the time, not for intellectual perception. Beauty is an affair of such perception; hence sensibility to beauty varies as much as the intellectual faculties themselves. For the inner truth of a representation, and its correspondence with the real nature of humanity, the mob has no sense at all. What is flat and superficial it can grasp, but the depths of human nature are opened to it in vain.
It is also to be observed that dramatic representations which depend for their value on their interest lose by repetition, because they are no longer able to arouse curiosity as to their course, since it is already known. To see them often, makes them stale and tedious. On the other hand, works of which the value lies in their beauty gain by repetition, as they are then more and more understood.

The reader, Andrew MacBeth, pronounces the name "SHOP-en-how-er" rather than SHOW-pen-how-er."
Three of the parables:
Two Chinamen traveling in Europe went to the theatre for the first time. One of them did nothing but study the machinery, and he succeeded in finding out how it was worked. The other tried to get at the meaning of the piece in spite of his ignorance of the language. Here you have the Astronomer and the Philosopher.
Once, as I was botanizing under an oak, I found amongst a number of other plants of similar height one that was dark in color, with tightly closed leaves and a stalk that was very straight and stiff. When I touched it, it said to me in firm tones: "Let me alone; I am not for your collection, like these plants to which Nature has given only a single year of life. I am a little oak."
So it is with a man whose influence is to last for hundreds of years. As a child, as a youth, often even as a full-grown man, nay, his whole life long, he goes about among his fellows, looking like them and seemingly as unimportant. But let him alone; he will not die. Time will come and bring those who know how to value him.
A number of porcupines huddled together for warmth on a cold day in winter; but, as they began to prick one another with their quills, they were obliged to disperse. However the cold drove them together again, when just the same thing happened. At last, after many turns of huddling and dispersing, they discovered that they would be best off by remaining at a little distance from one another. In the same way the need of society drives the human porcupines together, only to be mutually repelled by the many prickly and disagreeable qualities of their nature. The moderate distance which they at last discover to be the only tolerable condition of intercourse, is the code of politeness and fine manners; and those who transgress it are roughly told--in the English phrase--_to keep their distance_. By this arrangement the mutual need of warmth is only very moderately satisfied; but then people do not get pricked. A man who has some heat in himself prefers to remain outside, where he will neither prick other people nor get pricked himself.
It should be noted that Schopenhauer never lived with anybody throughout his entire adult life except for a series of poodles he named Atma - World Soul.
Also available - aphorisms:
How difficult it is to learn to understand oneself, and clearly to recognise what it is that one wants before anything else; what it is, therefore, that is most immediately necessary to our happiness; then what comes next; and what takes the third and the fourth place, and so on.
Yet, without this knowledge, our life is planless, like a captain without a compass.
If we were not all of us exaggeratedly interested in ourselves, life would be so uninteresting that no one could endure it.
A man is wise only on condition of living in a world full of fools.
